a flow guide air channel is arranged in the rapping body provided with the eccentric wheel;
continuously conveying air to the guide air channel, wherein the air flows in the guide air channel to form guide air, and the guide air drives the eccentric wheel to rotate;
the eccentric rotation of the eccentric wheel forces the rapping body to generate radial vibration, thereby realizing radial rapping;
stopping conveying air to the diversion air duct, and stopping the eccentric wheel from rotating;
the stop of air delivery to water conservancy diversion wind channel includes: blocking a radial outflow channel of the guide air duct; when the eccentric wheel stops rotating, the radial outflow channel is parallel to the radial direction of the eccentric wheel.
2. The radial rapping method of claim 1, wherein the air flows in a guide air duct forming a guide air, comprising:
air enters the diversion air channel along the axial direction of the eccentric wheel, and flows out of the diversion air channel along the radial direction of the eccentric wheel after the diversion air channel turns;
the water conservancy diversion wind drives the eccentric wheel rotation, include:
the air flow direction is changed after the steering, the air provides steering force for the eccentric wheel in the guide air channel, and the eccentric wheel rotates under the action of the steering force.
3. The radial rapping method of claim 1, wherein said blocking of the radial outflow channel of the guide duct comprises:
the barrier piece is placed in the rapping body, and the radial outflow channel is blocked by the barrier piece by utilizing the centrifugal force generated by the rotation of the rapping body.
4. A radial rapping method according to claim 1, wherein said radial outflow channel of the guide air duct is blocked, and the guide air flows out of the rapping body from the axial outflow channel of the guide air duct.
5. A radial rapping method according to claim 4, wherein the axial outflow channel of the guide duct is parallel to the inflow channel of the guide duct.
6. A radial rapping method according to claim 4, wherein the axial outflow channel of the guide duct is collinear with the inflow channel of the guide duct.
7. A radial rapping method according to claim 1, wherein the axial outflow channel of the air guide channel extends from one axial end of the rapping body to the opposite axial other end;
the radial outflow channel is arranged close to the other axial end;
and the axial outflow channel at the other axial end is blocked and the radial outflow channel is opened, so that the airflow is diverted from the axial outflow channel to the radial outflow channel and provides a steering force for the eccentric wheel.
8. A radial rapping method as defined in claim 7, wherein the axial outflow channel of the guide air duct communicates with the air duct of the drill rod, and the air flow flowing out of the rapping body from the axial outflow channel enters the air duct of the drill rod;
when the drilling rod is blocked or the card is dead, the wind channel of drilling rod is blockked up, and axial outflow passageway is obstructed, and the air current turns to radial outflow passageway from axial outflow passageway, the air current turns to do the eccentric wheel provides the power of turning to, eccentric rotation of eccentric wheel drives and shakes body and drilling rod radial vibration for the card of drilling rod hinders or the card is dead disappears.
